Hello everyone, I've just started trying PythonCard to build a simple GUI for a little application I'm writing. Just wondering if anyone knows the "proper" way to do some simple error checking: for example, I have a textField, and I wish to check that only integers within a certain range are entered into it.
I know I can just enclose that block of code in a try .. except clause, just that I'm not sure what to do once I've caught say, a ValueError exception. It certainly would not be a fatal error and I would like to prompt the user to re-enter the value, but how should I return to that point of program execution? Any help from the PythonCard gurus would be appreciated. Happy holidays!
